DAQmxCfgHandshakingTiming

int32 DAQmxCfgHandshakingTiming (TaskHandle taskHandle, int32 sampleMode, uInt64 sampsPerChanToAcquire);

Purpose

Determines the number of digital samples to acquire or generate using digital handshaking between the device and a peripheral device.

Parameters

Input

Name

Type

Description

taskHandle

TaskHandle

The task used in this function.

sampleMode

int32

Specifies whether the task acquires or generates samples continuously or if it acquires or generates a finite number of samples.

Value		Description
DAQmx_Val_FiniteSamps		Acquire or generate a finite number of samples.
DAQmx_Val_ContSamps		Acquire or generate samples until you stop the task.
DAQmx_Val_HWTimedSinglePoint		Acquire or generate samples continuously using hardware timing without a buffer. Hardware timed single point sample mode is supported only for the sample clock and change detection timing types.

sampsPerChanToAcquire

uInt64

The number of samples to acquire or generate for each channel in the task if sampleMode is DAQmx_Val_FiniteSamps. If sampleMode is DAQmx_Val_ContSamps, NI-DAQmx uses this value to determine the buffer size.

Return Value

Name	Type	Description
status	int32	The error code returned by the function in the event of an error or warning. A value of 0 indicates success. A positive value indicates a warning. A negative value indicates an error.
